CHARLES J. SEYMOUR, OF BROOKLINE, MASSACHUSETTS.

ELEVATOR AND CONVEYER.

SPECIFICATION forming part of Letters Patent No. 423,821, dated March18, 1890.

Application filed July 27, 1889.

I. To all whom it may concern.-

Be it known that 1, CHARLES J. SEYMOUR, of Brookline, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Elevators and Conveyors, of which the following is aspecification.

My invention relates to that class of machines or devices commonly knownas elevators and conveyers, being contrivances for raising coal, grain,860., out of a vessel or other receptacle, conveying it to a particularpoint, and depositing it in another receptacle.

My invention consists of a conveyer comprising an endless line or chainof pans or the like properly supported and moved and constructed andarranged to be separated at given points, the retreating and returninglines being connected again and adjusted at such separated points, so"as to discharge the coal, grain, or other substanceinto a chute at saidpoints.

My invention also consists of an elevatorhead of novel constructionadapted to such elevator-legs, in which the buckets and pans dischargetheir contents into a chute located between the ascending and descendinglines of such buckets and pans. Y

My invention will first be described in connection with the accompanyingdrawings, forming a part of this specification, and then pointed out inthe appended claims.

Of the drawings, Figure 1 is a vertical sectional view designed to showthe form and construction of my improved elevator-head, as also themanner in which my improvements are operated to take coal, grain, &c.,from one receptacle, elevate it, and convey it to and discharge it intoanother receptacle. Fig. 2 is a transverse section designed moreparticularly to illustrate the improved conveying and dischargingfeature of the device. Fig. 3 is a diagram of a feature of the inventionhereinafter more particularly referred to. Fig. 4 is a detail view ofthe elevator-head on an enlarged scale. Fig. 5 is a detail view show ingthe construction of the pans. Figs. 6, 7, and S are detail viewsshowingthe mannerin which the chain of pans maybe parted at any desiredpoints.

The same letters designate the same parts Serial No. 318,909. (Nomodel.)

or features, as the case may be,whereverthey occur.

In the drawings, a designates a receptacle for the transportation orstorage of coal, grain, &c'., and Z) another receptacle to which suchcoal, grain, 850., may be transferred.

0 is an elevator leg or frame at one end of the receptacle a, and d isan endless line or chain of buckets and pans constructed and arranged totravel to and fro the entire length of the receptacle a and receivematerial therefrom, and then to travel up, over, and down theelevator-leg c, discharging such material at the top of the elevator-leginto a chute e, by which it may be conducted to an endless line f ofpans or similar receptacles. This last-mentioned endless line or chainof pans is supported and travels upon suitable tracks 9, and is moved byand around sprocketwheels h h h 7L3, or similar devices, as will bereadily understood by reference to Fig. 2 of the drawings.

In order to be able to discharge the contents of the pans of the line fat various points, as is in practice desirable, I have so constructedand arranged said line as that it may be taken apart at given points andthe separated ends of the upper lines connected with the like ends ofthe lower line, passing such shortened endless line over sprocketwheels71. h or other suitable guides and forming a discharging-point for thepans at the outward extremity of the outward travel of the upper linebetween the wheels h 72. as indicated at 'i, Fig. 2.

When it is desired to cease discharging the contents of the pans at thepoint i and discharge the coal, grain, or the like taken from the chutea into the chute j at the point It, the line f passing around thesprocket-wheels h h will be severed at the point where they pass aroundthe last-mentioned wheel by the removal of an axle m between two pans,and the upper and lower lines connected by the replacement of an axle ineach, so as to form a continuous upper and lower line from the chute eto the point j, where the upper and lower lines will be disconnected andreunited, so as to travel around the sprocket-wheels h and h as shown.

In Figs. 5, G, 7, and 8 I have shown a construetion whereby the axles onmay be removed and the line of pans separated at any point.

To provide for the travel of the endless chain of pans around any of thesprocket wheels on the line, Iconstruct the upper track 9 with hinged orpivoted sections k, which will permit of removing aportion of said trackout of the way of the travel of the pans around the sprocket-wheels.Said hinged section of the track I have shown in Fig. 3 as constructedso as to be swung sidewise or outwardly, though said sections 7;. may bemade removable, so. as to be taken entirely out, the only thingnecessarybeing to get the upper track out of the way, so that thesevered upper and lower lines which have been readjusted around thesprocket-wheels may travel therearound unobstructed. By this means thecoal or other material in the pans can be discharged at any point of theconveyer-line where a sprocket-wheel or other guide is placed to guideor carry the line of pans around from theupper to the lower track. Saidsprocket or guide wheels may be placed at any point or points along theconveyerline, and power may be applied to any one or more of said wheelsin order to operate the chain of pans.

Any suitable means may be provided for tightening and loosening theendless line of pans running over the sprocket-wheels.

In order toprovide for the discharge of the buckets and pans carried upthe elevator-leg into a chute arranged between the ascending anddescending lines of said leg, I have provided an elevator-head of novelconstruction on the top of said leg, as shown in Fig.1, where thebuckets and pans are kept to the line of the circle described by thecircumfen ence of a wheel 1 until they are reversed to discharge theirload, when they are guided outwardly away from the ascending line on theleg or frame and around the chute c placed bet-ween the two lines,passing inwardly under said chute as near as may be desirable to theascending line, when they descend on a line parallel or substantiallyparallel to said ascending line.

Ihe guiding of the line of buckets and pans on the elevator-deg isaccomplished by means of the guides or tracks S. (See Fig. 4-.) In thisway an efficient contrivance is provided whereby the buckets and pansmay be made to discharge their contents between the as eending anddescending lines and the elevator-leg so constructed as to occupyaminimum amount of space.

It is obvious that changes may be made in the form and arrangement ofparts comprising my invention without departing from the nature orspirit thereof.

.llavin g thus explained the nature of my invention and described a wayof constructing and using the same, I declare that what I claim is- 1. Aconveyor consisting of an endless line of pans, wheels for guiding anddriving and tracks for supporting and guidin said endless line of pans,said tracks being made removable at intervals and said line of pans being constructed to be severed at said intervals and adjusted to travelaround said wheels, as set forth.

9. A conveyor consisting of an endless line of pans, sprocket-wheelsarranged at intervals along said line and adapted to engage the same,and chutes arranged at intervals corresponding to intervals at which thesprocket-wheels are arranged, said line of pans being constructed to besevered and united at intervals corresponding to the intervals at whichthe chutes are arranged, whereby the contents of the pans maybedischarged at different points, as set forth.

3. An elevator-leg adapted to guide ascending and descending lines ofbuckets, a guidewheel on the upper end of the said elevatorleg, and achute arranged beneath said guidewheel, the guides for said linesconstructed to guide the buckets over the said guide-wheel and chute andto discharge their contents in the latter, then outwardly from theascending line, and then around the side of the chute and inwardly anddownwardly beneath the same, as set forth.

l. An elevatorleg adapted to guide ascendin g and descending lines ofbuckets and pans, a guidc-whecl on the upper end of said elevatordeg,around which the lines of buckets and pans are adapted to travel, achute arranged beneath said guide-wheel, and guides or tracks arrangedto guide the line of buckets and pans around and beneath said chute anddump their contents in the latter, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 18th day of July, A. D.1955!.
